DAB/DAB+ Measurement

The DAB (Digital Audio Broadcasting) system originated at the 1980 German Institute of Radio Technology.
Based on the Eureka-147 system, DAB was developed to research terrestrial digital audio broadcasting
tech, and define an Eureka-147 DAB standard. It has seen wide adoption in Europe.
Following in the footsteps of AM (amplitude modulation) and FM (frequency modulation) broadcasting,
digital broadcasting presents the advantages of high spectrum utilization, anti-interference, encryption,
and the capacity for high-quality audio. The DAB standard uses the MPEG Audio Layer II coding method,
while DAB+ uses MPEG-4 High Efficiency AAC v2.
The S7200 supports both DAB and DAB+ measurements on the 1.536MHz band. The available frequency
range is 167.392 ~ 239.968 MHz – accurate to the nearest kHz.

When the signal is locked, the S7200 will automatically search for all programs, sub-channel ID, DAB type,
and encryption data of the selected channel. If audio issues are detected, tap Listen to activate the audio
feed. Use Vol+/- to adjust the volume.
